ABGs (Renal) Flashcards
what is compensation?
restore pH ASAP irrespective of what happens to the other values
what is correction?
restoration of the pH, pCO2 and HCO3
What is respiratory acidosis and the values for it
Retention of CO2 by the body
decrease in pH, increase in CO2, compensatory increase in HCO3
what are the causes of respiratory acidosis
chronic bronchitis, asthma, chronic emphysema, resp depression
What is respiratory alkalosis and what are values
Excess removal of CO2
increase in pH, decrease in CO2, compensatory decrease in HCO3
what are the causes of respiratory alkalosis
hyperventilation
with metabolic compensation what does an increase in H mean
and increase in HCO3 which means more HCO3 can be added to the blood - to increase pH (in rest acidosis)
with metabolic compensation what does a decrease in H mean
a decrease in PaCO2 means a decrease in H secretion which means decrease in HCO3 as it is secreted so no new HCO3 is added to the blood and HCO3 is being secreted meaning the pH is decreased
Metabolic acidosis values
decrease in pH decrease in HCO3 compensatory decrease in CO2
what is the compensatory action of metabolic acidosis
fast breathing to blow off CO2
Metabolic alkalosis values
increase in pH, increase in HCO3, compensatory increase in CO2
what is the compensatory action of metabolic alkalosis
slow breathing to retain CO2
